Change curve #23

Open cnasikas opened 5 years ago

cnasikas commented 5 years ago

Hi!

Is it possible to change the curve ie from BN128 to ALT_BN128 without modifying the pequin files ? Like -DCURVE=ALT_BN128 ?

Thanks in advanced

According to libsnark's documentation here, you'll need to rebuild libsnark with cmake -DCURVE=ALT_BN128.

Note, libsnark is built and installed as part of the pepper setup process at the end of this script.

Finally, add the appropriate flag to our Makefile here:

Thanks a lot for your answer. I am aware of the process you mentioned. I was wondering if it is possible to do it without modifying peppers's Makefile or installation script (probably not).

Thanks a lot!!

P.S: Feel free to close this issue if there is no alternative for the moment
